The invention relates to the technical field of textiles, in particular to a thermal insulation antibacterial fiber and a preparation method thereof. The thermal insulation antibacterial fiber is prepared from the following raw materials in parts by weight: 90 to 120 parts of polyethylene glycol terephthalate, 8 to 10 parts of cross-linked silicon dioxide aerogel and 20 to 30 parts of antibacterial master batch, the cross-linked silicon dioxide aerogel is obtained by cross-linking silane modified silicon dioxide aerogel and sodium metaaluminate; the antibacterial master batch is prepared from the following raw materials: chitosan quaternary ammonium salt, polyoxyethylene ether hyperbranched polymer modified cellulose and maleic anhydride grafted polyethylene; the mass ratio of the chitosan quaternary ammonium salt to the polyoxyethylene ether hyperbranched polymer modified cellulose to the maleic anhydride grafted polyethylene is 1: (1.5-2): (8-10). According to the thermal insulation antibacterial fiber prov
